opposition, appostition

Eager to instigate a conversation on what is meant by ability and disability and to what degree the senses and dexterity is hard-wired, a graduate student from New Zealand has created a prosthetic thumb that can enhance and extend one’s five-fingered capabilities.
This project is more than an academic pursuit, I think, given that the opposable pollex imparted a distinct evolutionary, manual advantage for humans. Presently, the device worn like a wrist-watch and is controlled by adjusting pressure in one’s feet—the coordination sort of like playing a musical instrument, which the extra thumb is also changing but could probably just as easily made subject to mental regulation and intention. I wonder what sort of phantom limb feelings might linger after trying out one of these prosthetics after getting accustomed to it.
